' IMPROVE) coax BXTRAGTOR.

TO WHOM IT MAY OONCERN:

Beit-known that I, JAMES WALKER, of Cincinnati, in the county of Hamilton, and State of' Ohio, have. invented a new anduseful Cork Extractor; und I' hereby declare the following -to be a full, clear, and exactl description lthereof, reference being hadito the accompanying drawings, making part of this speciii'cation.

My invention relates to a device for extracting corks lfrom bottles with much greater facility than heretofore, and less danger to the bottles as well as the operator. and without injury to thc screw or disturbance ofthe sediment. l l

Figure 1 is a perspective view of an apparatus embodying my improvement, a bottle 'being shown in position to receive the screw.

Figure 2 is an axial section, showing the screw entered and the-cork partly withdrawn.

From a base, A., arise two hollow vertical columns B B', in which slide two legs C C, united by a horizontal bar, D, to which is attached a hollow vertical cylinder, E, that receives and guides the stock F, of a cork- -screw G. The top of the stock has a crank or winch, H, by which it is rotated, and acallar, I, which projects'- beyond the cylindrical guides, and receives the impact of a pair of cams, J JV', that are pivoted horizontally to the outside of the guide, and are provided with a handle or lever, K. L are thimbles, of exactly equal external A diameter, to fit and occupy a socket, e, at the lower end of the guide E, but of diverse interior diameters to fit bottlesiof dii`erent-sized necks. The screw shank being flattened, is secured in a socket, and in the lower-end of thestock, by means of a key, M, so as to be easily taken out lfor sharpening or replacement, which .iv/ill, however, be seldom necessary, as Vthe screw, beingY fully protected from striking any hard substance, will with ordinary care lastin perfect condition for years. A p

The operation of theinstrument is as follows: The guide E being suiiiciently elevated, and a thimble of proper size being placed upon the top of the bottle, the latter is placed upon the base, and the lguide lowered down on to it; the crank H being then turned to the right, causes the screw to enter the cork accurately in the middle, and to penetrate thesarne in a vertical line1 which being truly axial in respect to the cork, does not split or ruil to one side thereof, nor wear out ,thc screw by grating against the side of the bottle. The screw having suiciently penetrated the cork, the latter is extracted by a semi-revolution of the lever K.- The bottle l being removed, the cork is disengaged from the screw by a rapid counter-revolution of the crank H, In practice, it is necessary to bringthe crank into a position coincident with theplane-of the standards before bringing the. lever K into play, which being eifecterl, the coi'k'serves to hold the crank to its proper plane during the process of' extraction.

Among a number of decided advantages of my extractor, the following may be cited t The screw entering the cork in a truly central line, and being guided unerringly to the precise centre of the cork, is neither liable to wear out by grating against the inside of the neck, nor to break the bottle inthe act of extraction. Thus .the bottle and its contents arer saved from destruction, and, what is of ,more serious consideration, the danger of wounding the hand and legs of the operator is avoided, and such wounds we well know to be both frequent and dangerous among victuallers and others having ldaily `occasion'to uncork many bottles. The bott-les being maintained perfectly at rest, the Acontents are not suused with the dregs, which by the customary mode are y shaken up and mingled with the contents of the bottle. The screw is entered by a continuous rotation pf the crank by the operator, without releasing his grasp, and the cork as quickly and easily extracted by a single semi-rotation of the lever H, the operation being easily performed by a lad or female, if desired. I have selected,

to-illustrate my invention, the form actually used by me, but the device is obviously susceptible of various modi..

fications; for example, a T head'or ordinary cork-screw handle may take the place of the crank. The cams J .I and lever K may be-formed of a single casting if desired.

I claim herein as new, and of, my invention- 1. The arrangement of adjustable guide E, cylindrical stock F, collar I, crank H, and cam-headed lever .I -J K, for the purpose set forth.

2. The provision, in combination with the above, of the thimbles L, of equal external but dissimilar interior diameters, as and for the purpose explained.

In testimony of which ,invention I hereunto set my hand.

JAMES WALKER.
